Can anyone talk to me about loans and when I should be worried about that?

I only want to take loans out for tuition. I have enough saved up in order to pay for room and board, including books, on my own. As of today, they've already sent me a letter about the loan system, but it's a little cryptic, and I'm wondering which loans are best.

Can I take it all out on Gradplus? Is it about 40k per year? What are you folks doing with your loans? Which have the lowest interest? (Sorry for the barrage of questions, but I'm trying to figure this out.)

Take as many stafford/perkins as you can. They are low interest, government subsidized rates. After that, I went grad plus for the rest - we had a variable and a flat interest rate one. They should be statistically the same, but I recommend taking the flat interest rate one due to the size of the loan and how long it will be before you pay it - interest rates could do anything in the next 6 years.

I cant really think of any good clues that wouldn't totally give it away. I guess I'll go with I am not from the midwest. I would be super impressed if you guessed who I am from what I have said thus far.
